A third person died Wednesday as a series of storms battered the Gulf Coast and South, forcing evacuations and high water rescues and leaving 25 million under the threat of flooding.

A 64-year-old man died outside Lucky, Louisiana, after driving through floodwaters on a road, the Bienville Parish Sheriff’s Office said. His 70-year-old passenger was found clinging to a tree and was rescued. The road was not barricaded, the sheriff’s office said.

Two others died in separate accidents across the region since the storms began sweeping through Monday, officials said.
